Answer 1

Answer:

First Winner take 31.95 minute time to complete race.

Step-by-step explanation:

Since the third winner take $34\frac{2}{3}$ minutes to complete the race.

Second winner take $1\frac{3}{4}$ minutes less than Third Winner.

Thus Second winner take $34\frac{2}{3}-1\frac{3}{4}\\  \frac{104}{3}-\frac{7}{4}\\ \frac{395}{12} =32.92 \ minutes$

Also, First winner take $1\frac{1}{3}$ minutes less time.

Thus first winner take time = $\frac{395}{12}-1\frac{1}{13}\\ \frac{395}{12}-\frac{14}{13}$=31.95 minutes
